Part Number: UCC2800-Q1 Other Parts Discussed in Thread: UCC2800 , UC3842A , UC3842 Hi HVC team,
Question above. The max duty cycle is 100%, is it possible to limit to 80% (for example)?
Thanks, Lauren
Hi,
Q1, UCC2891 VIN needs minimum 18V to start, if not using VIN, but VDD, it is minimum 13.2V. So for 9V input, you need to add external circuit to make UCC2891 to start
Q2, UCC2800, or UCC28C50
Q3, yes, or use TINA TI.
